XTC utilizes the same technology as Silver Anniversary X-Tube. With the removal of the silver plating and addition of extra wide conductor spacing it aims at a warmer and rounder sound compared to its more expensive sibling.

QED XTC Speaker Cable features the following QED Technologies:

99.999% Oxygen Free Copper

Speaker cables have to carry a lot of current. If the electrical resistance of the cable is too large, part of the music signal will be lost,

causing a detrimental effect on the fidelity of the sound you hear. To stop this from happening

we make the resistance of our speaker cables as small as possible. We do this by using the largest practical cross-sectional area of copper within the size constraints of each cable. In order to squeeze the last drop of performance from the conductors we make sure that there are no impurities in the copper which would defeat the object of making them so large. That’s why we use 99.999% oxygen free copper exclusively.

X-Tube Technology

In loudspeaker cables high pitched sounds are forced to travel towards the outside of the conductor and so are able to use less and less of the available cross-sectional area as the pitch increases. This is called the “Skin Effect”. It means that for high frequencies the resistance of the cable appears to be much higher than it does for lower pitched sounds. This has a detrimental effect on the fidelity of the sound you hear. QED X-Tube Technology solves this problem by creating a hollow tubular conductor geometry through which each frequency can pass with equal ease when compared to traditional solid or stranded conductors.

Airloc Technology

If a bare wire termination method is used the exposed copper quickly oxidizes increasing the resistance of the cable, which has a detrimental effect on the fidelity of the sound you hear. Available as an option, QED Airloc plugs eliminate this problem by preventing oxidization and providing a gold plated mating surface which remains low resistance for ever.
